Instead of the two vectors we manually composed, used a single unified
vector of structs to store delegate information in the model. This
simplifies the logic for tracking the active variant (and in the future,
thumbnail).
Search for the closest ground-net node near but /not/ on, the requested
runway. This works fairly well, although for some airports the selected
node is surprisingly far from the runway.
The report now looks like:
{
"meta": {
"type": "FlightGear JSON report",
"format major version": 1,
"format minor version": 0
},
...
}
When making compatible changes to the format (e.g., adding members to
JSON objects), only the minor version number should be increased.
Increase the major version number when a change is backward-incompatible
(such as the removal, renaming or semantic change of a member). Of
course, incompatible changes (like this one) should only be considered
as a last recourse.
- New methods Options::printJSONReport() and utility method
Options::OptionsPrivate::createJSONArrayFromPathList().
- Small addition to Options::processOptions(), since the --json-report
option must be processed *after* the TerraSync and download dirs, as
well as aircraft and scenery paths, have been finally set.
Apart from providing a public method giving a path to the autosave file,
the main idea of this commit is to reduce redundancy where
globals->get_fg_home() was so far used in every place where the autosave
file is needed or saved. Use an optional argument for
FGGlobals::loadUserSettings() and FGGlobals::saveUserSettings()[1],
since it should be exceptional to access an autosave file in another
location than $FG_HOME.
Also add comments explaining how to avoid security pitfalls with
saveUserSettings() (cf. discussion around
<https://sourceforge.net/p/flightgear/mailman/message/35461636/>).
[1] Argument *added* to this method, for consistency with
FGGlobals::loadUserSettings().
- The 'DatFilesGroupInfo' struct and 'DatFileType' enum are now public
members of 'NavDataCache'.
- New public method NavDataCache::getDatFilesInfo() returning the
'DatFilesGroupInfo' struct for a given type of dat files. For
instance, this allows one to retrieve the ordered list of apt.dat
files the NavCache would use if it were rebuilt at that time, as well
as their total size.
Similar to the existing FGGlobals::get/set_terrasync_dir(), add
FGGlobals::get_download_dir() and FGGlobals::set_download_dir() methods,
and of course the corresponding FGGlobals::download_dir public member
variable. FGGlobals::set_download_dir() stores the realpath() of the
given directory, including into the /sim/paths/download-dir property,
which is marked as read-only just as /sim/terrasync/scenery-dir already
is.
Handle the setup of the TerraSync and download dirs all in the same
place (Options::processOptions()), since most of the work is already
done there. This allows one to get rid of fgOptTerrasyncDir() and
fgOptDownloadDir(), and to make it easier to see that
globals->set_terrasync_dir() (resp. globals->set_download_dir()) is
called on the correct SGPath, regardless of whether --terrasync-dir
(resp. --download-dir) was passed.
Always create the TerraSync and download dirs when they don't already
exist, regardless of whether --terrasync-dir or --download-dir has been
given on the command line.
Add comments explaining how to avoid security pitfalls with download and
TerraSync dirs (cf. discussion around
<https://sourceforge.net/p/flightgear/mailman/message/35461636/>).
Adjust indentation where it was too broken, hampering readbility.
1) Paths and the FG_SCENERY paths list are now printed like:
FG_ROOT=/home/flo/flightgear/src/fgdata
instead of:
FG_ROOT=Path "/home/flo/flightgear/src/fgdata"
Moreover, FG_SCENERY is now correctly printed (without 'Path ""'
wrapping, without Terrain, Objects and markers instead of the actual
scenery paths) regardless of the position of --version relatively to
--fg-scenery, --terrasync-dir, etc. Of course, the values given to
these options do influence the output of --version.
Simplify printing of FG_SCENERY via SGPath::join() and use the
correct, OS-dependent separator between paths, SGPath::pathListSep.
Write the --version output to stdout, as already done for --help;
then it can be easily piped to $PAGER and doesn't get mixed with the
output of SG_LOG (which is on stderr). This is of course backward
incompatible for programs reading the stderr output of
'fgfs --version', but has been agreed upon on FlightGear-devel (cf.
<https://sourceforge.net/p/flightgear/mailman/message/35461619/>).
2) Don't write explicit values in the OptionResult enum: they don't
matter, but giving them is error-prone in case one does a copy-paste
to add a new member to the enum and forgets to change the value.
For some reason, g++ may see a 'skipws' I/O manipulator from the
standard library (depending on the order of includes...) when compiling
src/Navaids/poidb.cxx. This I/O manipulator is then in competition with
one with the same name defined in simgear/misc/sgstream.cxx. Use std::ws
to remove all ambiguity (std:skipws does something quite different!).
The new FGLight::updateObjects() function is now being passed into the global
events manager as a task rather than FGLight::updateSunPos(). The
updateSunPos() function has been renamed to updateBodyPos() and generalised for
any solar system body and is called twice by updateObjects(), once for the sun
and once for the moon. The local position of the moon is then exposed at
"/ephemeris/moon/local/".
This includes the moon's absolute position, age and phase. For this, the new
simgear MoonPos::get*() functions are tied to the property tree at
"/ephemeris/moon/" using a new tieMoonPos() function.
In addition the moon illumination factor is exposed by tying the simgear
MoonPos::getIlluminanceFactor() function to the /environment/moonlight property.
This is a number ranging between 0 and 1 based on the log of the illuminance of
the moon outside the atmosphere. It is calculated as
factor = (log(I) - max_loglux) / (max_loglux - min_loglux) + 1.0,
The illuminance of the moon outside the atmosphere, I, is from equation 20 from:
Krisciunas K. and Schaefer B.E. (1991). A model of the brightness of
moonlight, Publ. Astron. Soc. Pacif. 103(667), 1033-1039 (DOI:
http://dx.doi.org/10.1086/132921).

The functions fgSunPositionGST() and fgTimeSecondsUntilSunAngle() have been
renamed to fgBodyPositionGST() and fgBodyPositionGST() respectively, and both
require a new char argument specifying the body of interest. This allows the
position of all solar system bodies to be calculated from the aircraft frame of
reference.
Add option --print-solidness
without this option, behaviour of fgelev is unchanged
with this option the word "solid" gets printed behind the elevation if the
material at the given location is solid. A hyphen (-) gets printed otherwise
Move the existing aircraft history to a more obvious place, and follow
the same pattern for the complete location history. This makes restoring
a previously used configuration much simpler.
Of fast systems with 60fps sending many properties to web clients
